Founded in 1969 as East Joliet Bank, Merchants and Manufacturers Bank (M&M Bank) started as a traditional, locally owned bank that valued its roles and responsibilities as a community bank. The Bank primarily operated as a local bank throughout the Seventies before being acquired by a bank consolidator in the Eighties. The current ownership took control of the bank in 1993 and brought a focused expertise in business banking and a commitment to maintaining the principles of community banking that the institution was founded on.
